NEET Physics Kirchhoff's Laws MCQ Question
Which of the following statements about Kirchhoff's Laws is correct?
The sum of the emf in any closed loop is equal to the sum of the potential drops across the resistances.
The current entering a junction must be greater than the current leaving the junction.
In a parallel circuit, the total current is equal to the sum of the currents through each branch.
All cells in a parallel circuit must have the same emf to apply Kirchhoff's Laws.
Correct Answer
Detailed Explanation
According to Kirchhoff's Laws, particularly the loop rule, the sum of the electromotive forces (emf) and potential drops around a closed loop must be zero, which aligns with option A. Options B and D reflect misconceptions about current and cell configurations, while option C is true but does not directly relate to the laws themselves.
